Incidence and risk factors of C. trachomatis and N. gonorrhoeae among young women from the Western Cape, South Africa: The EVRI study

Objective Young women in South Africa are highly affected by sexually transmitted infections (STI), like C. trachomatis (CT) and N. gonorrhoeae (NG). We aimed to estimate the incidence of CT and NG, and its determinants, among young women from the Western Cape, South Africa, participating in an HPV vaccine trial (the EVRI study). Methods HIV-negative women aged 16-24 years were enrolled between October 2012 and July 2013. At enrolment and month 6 participants were screened for CT and NG (Anyplex CT/ NG real-time detection method). A questionnaire on demographic and sexual history characteristics was completed at enrolment and month 7. Treatment for CT and/or NG was offered to infected participants. Incidence rates (IR) of CT and NG were estimated. Determinants of incident CT and NG infections were assessed using Poisson regression. Results 365 women were tested for CT and/or NG at least twice. Prevalence of CT and NG at baseline was 33.7% and 10.4%, respectively. Prevalence of co-infection with CT and NG was 7.1%. During 113.3 person-years (py), 48 incident CT infections were diagnosed (IR = 42.4 per 100 py, 95% confidence interval (CI) 31.9-56.2). Twenty-nine incident NG were diagnosed during 139.3 py (IR = 20.8 per 100 py, 95%CI 14.5-29.9). Prevalent CT infection at baseline was associated with incident CT (adjusted incidence rate ratio (aIRR) 5.8, 95%CI 3.0-11.23. More than three lifetime sex partners increased the risk for incident NG (3-4 partners aIRR = 7.3, 95%CI 2.1-26.0; > 5 partners aIRR = 4.3, 95%CI 1.1-17.5). Conclusions The IR of bacterial STIs among young women in the Western Cape is very high. Besides being previously infected and a higher lifetime number of sex partners, no other risk factors were found for CT and NG, suggesting that the majority of these women were at risk. This indicates the need for intensified prevention of STIs as well as screening and treatment programs to increase sexual health in this region

Hypertension in a rural community in South Africa: what they know, what they think they know and what they recommend

Abstract Background Hypertension is one of the most important risk factors for cardiovascular disease and has a high prevalence in South Africa and other low- and middle-income countries. However, awareness of hypertension has been reported to be low. Health programmes can increase awareness of hypertension and its causes, but hinge on the knowledge and perception of the targeted community. Therefore, this study investigated knowledge on and perceptions about hypertension of community members in a rural area in Limpopo, South Africa with the aim to increase awareness of hypertension and cardiovascular disease in the local population. Methods Using a mixed methods study approach, 451 participants of the Ndlovu Cohort Study, attending a follow-up visit between August 2017 and January 2018, completed a questionnaire on cardiovascular risk perception. A knowledge score was calculated for all participants. Sixty participants were invited to participate in six focus group discussions, of which 56 participated. Audio recordings were transcribed verbatim, transcripts coded, and thematic analysis of the data undertaken to obtain an understanding of knowledge and perception of hypertension in the community. Results Most members of the community seemed to have intermediate (74.3%) or good (14.0%) knowledge of hypertension based on the knowledge score, and only 11.8% of the population had poor knowledge. The risk factors of hypertension seemed to be well known in the community. Poverty was identified as a major vulnerability in this community limiting choices for healthy lifestyles such as nutritious foods, recreational physical activity and accessing health care timely. Participants proposed community-based activities as an effective way to reach out to community members for prevention and management of hypertension. Conclusion This study highlights the need for improved health promotion efforts to increase knowledge of hypertension in rural communities, and to address poverty as a major obstacle to healthy life-style choices

Decision-making regarding condom use among daily and event-driven users of preexposure prophylaxis in the Netherlands

OBJECTIVE: To explore the frequency of and reasons for using condoms among men who have sex with men (MSM) on preexposure prophylaxis (PrEP). DESIGN: We analyzed quantitative app-based diary data on daily sexual practices (August 2015-February 2019) and qualitative in-depth interviews among MSM using daily PrEP and event-driven PrEP (edPrEP) in the Amsterdam PrEP demonstration project. METHODS: Participants could report daily about sex acts, PrEP use and condom use per partner type (steady and casual partners). We examined four strategies of PrEP and condom use: PrEP only, PrEP and condoms, condoms only, and neither strategy. We compared the proportions of sex acts per strategy between PrEP regimens. In 43 in-depth interviews, we explored motives for implementing each strategy. RESULTS: Three hundred and fifty-two participants reported 48 949 anal sex acts. PrEP only was the most common strategy employed with any partner type (81%, n = 39 650/48 949) and was motivated by anticipating more pleasurable sex, sexually transmitted infection's perceived curability, and habituation to condomless sex. Combining PrEP and condoms was more often chosen for sex acts with casual partners (18%, n = 6829/37 317) than with steady partners (5%, n = 614/11 632) and was linked to, for example, higher perceived vulnerability for sexually transmitted infections or HIV and avoidance of PrEP disclosure. Condoms only was uncommon but occurred particularly among edPrEP users (4%, n = 379/8695). Applying neither strategy was common among edPrEP users with steady partners (25%, n = 538/2122) and was motivated by low perceived HIV risk. CONCLUSION: Condoms remain a viable option for PrEP users in certain settings. Condoms were applied in higher risk settings, to avoid PrEP disclosure, or as substitute for PrEP, especially among edPrEP users

Human papillomavirus vaccination uptake: a longitudinal study showing ethnic differences in the influence of the intention-to-vaccinate among parent-daughter dyads

Introduction: It is unclear what role daughters play in the decision-making process regarding HPV vaccination. Therefore, we explored the impact of HPV vaccination intention among parents and their 12–13 year-old daughters on HPV vaccination uptake. Methods: In February 2014 parents/guardians and their 12–13 year-old daughters were invited to complete a questionnaire about socio-psychological determinants of the decision-making process regarding HPV vaccination. Vaccination status of the daughter was retrieved from the national vaccination database after the last possible vaccination date in 2014. The association between HPV vaccination uptake and intention, and determinants of intention, was jointly assessed using a generalized structural equation model, stratified by origin of parents (Dutch versus non-Dutch). Results: In total, 273 Dutch parent-daughter dyads and 165 non-Dutch dyads were analyzed for this study. HPV vaccination uptake was 90% (246/273) and 84% (139/165) in the Dutch and non-Dutch group, respectively. In the Dutch group, high parental intention (β = 2.3, 95%CI 1.2–3.3) and high daughters’ intention (β = 1.5, 95%CI 0.41–2.6) were significantly associated with HPV vaccination uptake. In the non-Dutch group, high daughters’ intention (β = 1.2, 95%CI 0.16–2.2) was significantly associated with HPV vaccination, but high parental intention was not (β = 0.52, 95%CI −0.47–1.5). Attitude was the most prominent socio-psychological determinant associated with vaccination intention among all groups. Conclusion: In the non-Dutch group, only daughters’ intention was significantly associated with HPV vaccination uptake, whereas in the Dutch group both the parents’ and the daughters’ intention were significantly associated with uptake. The role of the child in the decision-making process might need to be taken into account when developing new interventions focused on increasing HPV vaccination uptake, especially among individuals of non-Dutch origin
